I-ADVISE

What I-ADVISE does

I-ADVISE AG Wirtschaftsprüfungsgesellschaft is an independent German accounting and advisory firm founded in 2007 and headquartered in Düsseldorf, with a second office in Frankfurt. The firm operates a partner-led, project-based professional services model across four interconnected service lines: M&A Advisory (buy-side and sell-side transaction support), CFO Advisory Services (pre-deal preparation, exit readiness, post-merger integration, financial modeling), Transaction Services (financial and tax due diligence, fact books, vendor due diligence, tax structuring), and Valuation Services (IDW-compliant statutory, fairness opinion, purchase price allocation, and tax-driven valuations). Underlying technology is limited to proprietary valuation frameworks and a published monthly base rate calculation methodology following IDW S1 recommendations using Deutsche Bundesbank yield curve data via the Svensson method, supplemented by recurring proprietary research studies on German valuation practice, implicit market risk premiums for European and US indices, and sector-specific valuation spotlights.

Revenue is generated entirely through customized, quote-driven professional services engagements priced on transaction complexity, scope, team seniority, and duration, typically structured as multi-year mandates. Go-to-market is consultative and direct: senior partners lead business development through personal networks, professional referrals, industry events, and thought-leadership content distribution. The client base spans large international corporates, listed companies (including DAX and M-DAX constituents), private equity and venture capital firms and their portfolio companies, family offices, and German Mittelstand / mid-cap companies. Cross-border transactions are served through a mutual cooperation agreement with Stout Risius Ross (US) and an international alliance of cooperation partners in 10+ countries. The firm has completed over 100 cumulative M&A and valuation engagements across manufacturing, energy, automotive, healthcare, retail, IT services, aerospace, and publishing sectors. Headcount is in the 11-50 range with a partner cohort drawn predominantly from Big Four firms (KPMG, EY, Deloitte, PwC, Arthur Andersen).
